Be it known that I, EDWARD P. Donner LAN, citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful lmproven'ients in Counting and 1'. dohereby declare the following be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to Whichit'appertains to make and use the same, reference being had to theaccompanying drawings, and to characters of refe 'ence marked thereon,

which form a part of this specification.

This invention relates, generally, to im-- provements in countingmachines for counting flat disc-like objects, such as coins, buttons,tokens, etc, in lots of predetermined number.

The invention has for its principal object to provide a novel tallyingor counting mechanism for countin machines combined with automatic stopdevices therefor, whereby the operation ofthe tallying mechanism isautomatically interrupted and the machine stopped or lockedagainstfurther operation after any desired predetermined number of coinsor other articles have been counted.

Other objects of this invention, not at this time more particularlyenumerated, Will be clearly understood from the tailed description ofthe same.

lVit-h the objects of the invention in view, the same consists,primarily, in the novel improved tallying mechanism forcounting machineshereinafter set forth; and, furthermore, this invention consists in thenovel arrangements and combinations of the various parts, as well as inthe details of the construction thereof, all of which will behereinafter more fully described in the following specification, andthen finally embodied in the claims which are appended thereto.

' The'inventionis clearly illustrated in the accompanying drawings, inWhich:---

Figure 1 is a plan View of the novel com bined tallying and automaticstop mechanisin for counting machines, made according to and embodyingthe principles of this invention; Figure 2 is a part plan and parthorizontal section tlrough the same. Figure 3 is a vertical longitudinalsection through the same,talren on line. 33 in Figure 1;

.tallying mechanism is operated. The novel tallying and automatic stopmechanism embodying the principles of the present invention, is designedto operate in such a manner that the same may be set to count apredetermined number of articles and then auto matically lock itself andthe counting ma chine against further operation until released; and,furthermore, the stop mechanism may be set to function upon the countingof any desired number of coins, either in odd or even numbers; in otherwords the stop mechanism may be set and operated according to thepredetermined number of units desired to be counted, rather thanaccording to decimal multiples of units as in my previous machines; and,furthermore, the arrangement is such that the mechanism may be quicklyand easily set for continuous counting, if desired.

In the drawings, the reference character 1 indicates the baseplate ofthe machine.

Journaled in said baseplate is a vertical spindle 2 upon which is fixeda star-wheel or counter disc 3 a series of marginal depressionseladapted to be engaged by the perimeters of the articles forced intoactuating contact therewith by the propelling mechanism of the machine(the latter not being shown). Preferably said marginal depressions areten in number. Suitably located upon said bedplate 1, so as to projectupwardly therefrom, is a vertical journal stud 5. Rotatably journaledupon said stud 5 is" a counter gearprovided in its periphery with ilock-ratchet wheel 11, of slightly smaller di- 7 wheel 6 which mesheswith aspur gear 7 fixed upon said spindle 2. Said counter gear wheel 6has a ratio of revolution to said spur gear 7 of one to ten, i. c., saidspur gear, ,as actuated by said star-wheel or counter disc 3, makes tenrevolutions to produce one revolution of said counter gearwheel 6. Fixedupon said spindle 2' is a ratchet wheel 8, which is engaged by aspring-pressed pawl 9, pivoted upon said base-plate 1, which serves toprevent rotation ofsaid star-wheel or counter disc, 3 in a backwarddirection, and consequently also prevents any backward movement of thecounter-gear wheelG which is actuated by said star-wheel or countendisc.

Secured upon the upper face of said counter gear-wheel 6,'by screws 10or any other suitable fastening means, so that it rotates witl-rthecounter gear-wheel 6, is a ameter than'the diameter of: said'countergear-wheel 6.

The retercncc'character :12 indicates suitable casing mi cover forenclosing the counter-gear mechanism above described,

and which is also adapted to serve as a support for additional elementsof the tallying mechanism. Fixed upon the upper outer side of saidcasing or cover 12 1s a scale-plate 13,'provided in its upper side withan annular inverted T-shaped groove or channel 1 1. The outer marginalportions of the upper side of said scale-plate13 is provided with agraduated scale 15, which divides the same into divisions, each divisioncorresponding to the movement oi" the counting mechanism produced by theactuation thereof by a single article. in the illustration of theinvention as shown in the drawings, the scale is marked oil to provideone hundred divisions, the mechanism being arranged so thatactuationofthe starwheel O1\COllIl1lI disc '3 by one hundred articleswill produce one complete revolution of the counter gear wheel 6.

Itota'tably mounted upon the upper end of said journal stud 5 is'a stopcontrol disc 16, to the underside of which is fixed a latchratchet-wheel '17 of somewhat larger diaineter than said stopwlisc butsmaller in diameter than said lock-ratchet wheel 11.

'Said stop control disc 16 with its latch fixed upon'the upper surfaceof said loci: ratchet-wheel 11, so that'saidl'atch member 18 willoperatively engage the'teet-h of said latch ratchet-wheel 17 The casingorcover 12 is provided with a centralopening and in likenianner theannular scale-plate 13 provides a central opening alined with saidcasing opening 20. Said stop control.

disc 16 isprovided on its upper s de with a hub portion 21,whichprojects upwardly through the openings in said casing andsaidscale-plate, and 1 upper extremity with a square shank v'llicli'projects above the upper surt'acc' ot said scale-plate 13; Fixed onsaidstop control disclG, so as to surround'its hub 21 and the sameisprovided'at its v so as to be positioned in the openingotsai'dscale-plate 13,1 flush therewith, is a filler block 23, which rotateswitlrsa d stop-disc; Ad ust ably mounted on said 'sguare;-shank-' 22 isa radially extending" stop-plate'fls'n Said stop-plate2 i is provided inits body portion with a rectangularopening or slot 7 '25 toreceive saidsquare -sl1ank22,;so that 7' on said'square shank to either normal" thestop-plate 24- is longitudinally movable outwardly projectedpositionftasshown by the full lines in Figure 1), or to a retracted position (asshown by the dottedllines in said Figure 1-). The means for holding thestop-plate 24 in either one-er the other of its two positions,comprisesaspring pressed latch-memberflti, the casing or barrel 26 ofwhich is fixed upon the upper surface of said filler block 23, so thatthe latch-member is normally pressed toward 'one side of said stop plate9A, said'side being providedwith an indented notch 27 .engageable bysaid f latch-member to hold "the stop-plate 24 in normal forwardlyprojected position, and a secondindented notch28 engageable bysaidlatch-'n'iember to hold the stop-plate '24: in-' its retracted position.Said st-op platei "is provided at its outer free end with, a stop-proection 29, which terminates in a pointer member 30 normally adapted iLOCO- is operate with the'graduated'scale 15- ot the scale-plate 13.Adjustably movable'in said groove or 'cha-nnel 14 of said. scalepla'te13 V is a stop-post device, thesamecomprislng a threaded shank "31having {a T-head" at; its'lower enddisposed in said groove or '5 channel1%, and threaded 'onisaidxshank 31' is a lock-nut 33, jVlllCli, whenscrewed-down,

cured t-othe hub'21 of said step control-disc" 16, abovesaidstopplatef24-,is a knob or finger-piece 3 1. 1

Mounted on said base-plate '1, at one side of said counter gear-wheel'G'and associated I parts as above described is a bracket 35' forsupporting barrel 36 provided witha guide way 37 open towardthe'coun'ter gear whecl mechanism. Slidable in said guideway 37 is alock-plunger 38, having at its lower outer free end lock-teeth 39,adapted at proper times to engage or intermesh with the teeth of saidlock ratchet-wheel 11 to thereby prevent operative movement of thecounter gear-wheel mechanism. The rear end of said lock-plunger 38 isprovided with a stem 40 which extends outwardly through the rear endwall of said barrel 36, its outer endhaving a knob or finger-piece 41.The upper side of said lock-plunger 38 is provided with a groove 42 inwhich is engaged by the end of a stop screw 43 connected with saidbarrel 36, so that the longitudinal movement of said lock-plunger 38 isproperly limited. A compression spring 4 1, arranged intermediate therear end of said lock-plunger and the rear end wall of said barrel,exerts a normally outward thrusting pressureupon said lock-plunger.Connected with the upper forward end of said lock-plunger is a forwardlyprojecting control rod 45, the free end of which is pro vided withanosing 46 which engages the periphery of said stop control disc 16.Said stop control disc 16- is provided in its periphery with an indentednotch 47 which,

at proper times, receives said nosing 46 of,

the control rod 45. Pivotally mounted on said stop control disc 16 is ahold-out pawl 48, which is provided with a lip 49 extending downwardlyover the periphery of said stop control disc 16. Said hold-out pawl 48is normally actuated by a compression spring 50 to yieldably retain thesame against a stop-pin 51, in which position the lip 49 closes over thenotch 47 in the periphery of said stop control disc 16. The stem 40 ofthe lock-plunger 38 is provided with a cross-pin 52in its externalportion. Rotatably engaged on said stem 40 abutting the rearward end ofsaid barrel 36 is a collar 53 provided in its outer face with atransverse groove 5a in which said crosspin 52 is normally engaged orseated. In order to hold the lock-plunger 38 in an inoperative position,as is necessary when it is desired to operate the counting machine forcontinuous or uninterrupted counting, said stem 40 and the lock-plunger38 is retracted and the collar 53 is turned to remove the groove 54 fromthe path of saidcrosspin 52, so that the latter rests against the outerface of the collar 53, thus retaining said lock-plunger in retracted andinoperative relation to the: counter gear-wheel mechanism.

Mounted on said baseplate' 1 in a suitable location is a handmanipulatable pivoted stop dog 55 which may be turned toengage'the teethof the'lock ratchet-wheel ll to hold the counter gear-wheel mechanisminoperative, under circumstances subsequently to be described.

The operation of the above described counting mechanism is as follows z-Assume that it is desired to count twentyfive articles, and have thecounting mechanism automatically lock the against further delivery ofarticles upon the counting and passing out of the machine of thetwenty-fifth article. The knob 34 is turned to position the pointermember 30 of the stop-plate 24 upon the twenty-fifth division of thescale 15, and then the stoppost device is moved against the stopprojection 29 and locked relative to the groove or channel 14 of thescale plate 13 (the stop-plate 2 L occupying its normal forwardlyprojecting position so as to properly engage said stop-post device). Inturning the stop-plate 24- to the above-described po-' sition, the stopcontrol disc 16 is turned back to remove the stop-notch ion distant fromthe control rod 45 equivalent tothat requiring the actuating engagementof twenty-five articles with the counting mechanism to rotate the stopcontrol disc in operative direction back to normal initial stoppedengagement with the said control rod 45. In so turning back the stopcontrol disc 16 the control rod nosing 46 rides out or" the notch at? onto the periphcry of the stop control disc, thereby thrusting back thecontrol rod 4:5, and in turn retracting the lock-plunger 38 to removethe lock-teeth 39 thereof from looking engagement with the teeth of thelock ratchetwheel 11, thus freeing the counter gearwheel 6 for forwardmovement, and consequently releasing the entire counting mechanism andcoin delivery mechanism of the machine for operative movement. If thecounting machine is hand driven, the operator now actuates the samethereby causing the articles to be counted to be successively deliveredin passing and actuating engagement with the star-wheel or counterdisc3, thus rotating the same, and thereby transmitting through the spurgear 7, a forward rotative movement to the counter gear-wheel 6. As thecounter gear-wheel 6 rotates, the stop control disc 1.6 and associatedparts turn with it, since the pawl 18 interlocks with the latchratchet-wheel 17 to cause the stop control disc 16 and countergear-wheel to move together in operative direction, thus returning thenotch 47 back toward the control rod As the twenty-fifth article passesthe star-wheel or counter-disk 3, the stop control disc 16 has moved itsnotch 17 into line with the nosing 46 of the control rod l5, so that thespring 4% exerting its pressure upon the lock-plunger 38 thrusts thelatter forward, such movement being permitted by the entrance of thecontrol rod nosing 16 into said notch e7. This forward movement of thelocleplungcr carries the teeth ma chine 17 to a posi 39 thereof intooperative meshing engage ment with the teeth of the. lock ratchet- Wheel11, thereby locking the countergear- 'Wheel against further forwardrotation, and

consequently holding the star-wheel or counter disc 3 against furtheroperative'movement, so that the machine is locked against furtherdelivery and counting of articles,

after completing the count of the desired controldisc 16 untilthe stopprojection 29 engages thestop-post device, whereupon the machine is setto repeat the above described operations. This may berdone as often asdesired.

It will be understood that itit is desired to countthe articles in lotsof any desired odd or even number, the stop-plate 2%: is

initially turned back to the number on the 7 scale corresponding to Ithe number. of

articles making up the desired lot, and then the stop device isset tocorrespond to the.

initially set position oi? the stop-plate thus determined, whereupon themachine may be operated repeatedly in the manner above described.

- In the event the machine is of the motor driven type, so that themechanism delivering the articles past the star-wheel or counter-disc 3runs continuously, it is necessary, after the completion of the countingof the desired lot of art1cles,'tothrow the stop-dog into holdingengagement with the teeth of the lock ratchet-Wheel 11, to

thereby hold the counter gear-Wheel 6 against operatlve movement whilethelockplunger 38 is released therefrom duringthe resetting of the'stopcontrol disc 16. After therstop control disc is reset, the stop-dog isreleasechsothat the machine and count ng mechanism immediately begins tofunction.

"lVhen it is desired to count out the articles in lots of one-hundred,the maximunrlot numher arranged for in the illustrated form of themechanism," the stop-plate 24G 1s retracted to the dotted position shownin Flgl.i16 1, in which position the stop pro jection 29 and pointermember 36 isgivith drawnsoas, to clear "or pass the stop-device e of thescale-plate 18.

the knob ll is utilized to retract the lockplunger 38, thus releasingthe loclcteeth 39 ,thereof from holding engagement with the To beginoperations,

teeth of the lock ratchet-Wheel 11, while at the same'time Withdrawingthe nosing .46

of the control rod 415 from the notch 4:7 of

' [the stop control disc 16. When the nosing pa vl 4-8 isthrus-t by thespring 50 against i6 is removed from the notch 4:7, the holdoutthe'stop-pin 51, in which position the lip l9 covers the notch 4 -7 and"prevents re-entrance ofthe' nosingback into the notch 47, thus:maintaining the counting mechanism released for operation. Tlie'operator now actuates the machine to deliver the articles successivelyinto actuating engagement With the star-Wheel or counter disc 3, sothat; the counter gear-Wheel 6 andthe stop control disc 16 are rotatedina forward direction. The rotation of the stop control disc 16 carriesthe lip 49 of the hold-out pawl 48 away from the nosing 46 of thecontrol rod 45 permitting .the latter to engage the. periphery of thestop control disc 16 beyond the notch 17. Since the countingoflonehundred article'sxvvill produce one, complete revolution of th'e'counter gear-Wheel 1 and stop control disc, the. notch 47 is againthenotch 1-7 is again registered opposite the nosing 46, so thatthelattermay enter there in, whereupon the lock-plunger again moves intolocking relation to the lock ratchet- Wheel 11. As the notch.alisiapproaching 7 the spring 50, and therebyeirposes the notch 417' tothe entrance of the nosing ati therein.
